I Give You a Coin, and You Flip It 100

Question 4

Multiple Choice

I give you a coin, and you flip it 100 times. Let X = the number of heads observed in those 100 flips. You build the following line of reasoning:
Steps
1) You assume each flip is an independent, random outcome.
2) You assume the coin is fair.
3) Using your statistics book, you conclude that X is distributed binomial with mean 50 and variance 25.
4) Based on this distribution, you conclude that you would observe X < 41 or X > 59 approximately 5% of the time.
5) You observe X = 37 and conclude that the probability that X < 41 or X > 59 is not 5%.
6) Because the probability that X < 41 or X > 59 is not 5%, you conclude the coin is not fair.
Which of these steps is part of inductive reasoning?


A) Step 5 only
B) Steps 5 and 6 only
C) Steps 1, 2, and 3 only
D) Step 6 only
